Abstract

An arrangement in a television receiver in which a sychronized external power stage supplies operating voltage to a remote-control receiver and a microprocessor connected thereto. A horizontal drive circuit is controlled by the microprocessor, and a horizontal end stage is connected to the horizontal drive circuit. The external power stage supplies power during stand-by operation only to the remote-control receiver and microprocessor along with the voltage for operating the horizontal drive circuit and the end stage. Thyristors are connected to the external power stage for supplying power to all other circuit stages in the television receiver. The thyristors have gate electrodes activated by the horizontal end stage for cutting off the thyristors during the stand-by operation and interrupting the supply of power to all other circuit stages in the television receiver, for minimizing the power consumption of the television receiver.
